How to create a while loop in a student program and interrupt it when you stop typing data

It's a program that calculates the average of a group and that can break the cycle whenever it wants to](Https://i.stack.imgur.com/L0typ.png)

javascript – Why does this script have to execute the last loop 50 times before realistically

I made myself a simple script (Batch / JScript) that downloads an image from a blog (APOD) and sets it as a screen background.

@if (@a == @ b) @end / *

Set BaseUrl = https: //apod.nasa.gov/apod/
set yr =% date: ~ 8.2%
set mn =% date: ~ 3,2%
set dy =% date: ~ 0.2%
set dte =% yr %% mn %% dy%
set SaveDest = C:  Users  ME  Desktop  Wallpaper % dte% .jpg
Set the URL =% baseUrl% ap% dte% .html


@ Echo off
setlocal
for / f "delims =" %% I in (cscript / nologo / e: jscript "% ~ f0" "% Url%" & # 39;) do (
rem
echo %% I
set LastImg = %% I
)

set ImgUrl =% BaseUrl %% LastImg: ~ 6%
bitsadmin.exe / transfer GETWALLPAPER% ImgUrl %% SaveDest%
timeout / t 01
Add reg "HKEY_CURRENT_USER  Control Panel  Desktop" / v Wallpaper / t REG_SZ / d% Savedest% / f
timeout / t 01
for / l %% x in (1,1,80) do (
RUNDLL32.EXE USER32.DLL, UpdatePerUserSystemParameters
Add reg "HKEY_CURRENT_USER  Control Panel  Desktop" / v Wallpaper / t REG_SZ / d% Savedest% / f
timeout / t 01
)

goto: EOF

JScript * /
search function (url) {
var xhr = WSH.CreateObject ("Microsoft.XMLHTTP");
var dom = WSH.CreateObject (& # 39; htmlfile & # 39;);
xhr.open ("GET", WSH.Arguments (0), true);
xhr.setRequestHeader ('User-Agent', 'XMLHTTP / 1.0');
xhr.send (& # 39;);
while (xhr.readyState! = 4) {WSH.Sleep (25)};
dom.write (& # 39;& # 39;);
dom.write (xhr.responseText);
return dom;
}
var dom = fetch (WSH.Arguments (0));
var link = dom.getElementsByTagName (& # 39; IMG & # 39;);

WSH.Echo (link[0].src);

It works. However, the last batch line where I update the registry does not work without the loop. An idea ?

NB: Your code does not look like my hybrid script. The first part is not a comment until JS has read the file. I do not know how to solve that.

8 – PHP for each loop in loop

Can any one suggest how to convert the following php code to a twig field template.

    $ item) {
foreach ($ item['entity']['test_item']    as $ p_key => $ paragraph) {
$ bundle = $ item['entity']['test_item'][$p_key]["#bundle"];
if ($ bundle == "add_testing") {
$ newtest[] = $ item['entity']['test_item'];
} else if ($ bundle == "my_section") {
$ test[] = $ item['entity']['test_item'];
}
}
}
?>

temporal complexity – Relative efficiency of n tasks in 1 loop versus 1 task each in n loops?

Let's say I have 3 simple tasks, find the min, the max and the average of an array of numbers.

A modular approach would be to write a function for each, thus iterating the table three times. However, this seems unnecessary if all information can be collected in a single iteration.

I understand that both approaches take 3n but I wonder if one approach is better than the other in the general case and why.

7 – Execute a while loop, show all results

I have this while loop.

while ($ row = $ result-> fetchAssoc ()) {
echo $ row['field_icon_value'];
echo $ row['field_usp_title_value'];
}   

I would like to run this all in loop in this $ usp variable as a list item. Is it possible to interrupt the $ usp execute while loop?

$ usp = & # 39;
    
& # 39 ;; $ content['content'] = $ usp;

So, my code looks like this:

$ usp = & # 39;
    
    ** Loop here .. **
  • & # 39 ;. $ row['field_icon_value'] . $ row['field_usp_title_value'] & # 39;
& # 39 ;; $ content['content'] = $ usp;

loop – How to parallelize at different levels in R?

I've researched how to put in parallel for on R and found the package for eachwhich, from what I understood and corrects me if it is false, replaces the for as following:

library (foreach)
vector <-rep (NA, 10)
n <-seq_len (10)
foreach (j = n)% dopar% {
vector[j]<-j + 1
}

My question how to do in a case where I've for () {for () {}}, for () {for () {for () {}}}… Is it possible to repartition?

postgresql – Inserts a value every minute (for loop or generate_series)

I'm trying backup and restore using WAL-E / WAL-G.

I can backup and restore.

But I want to check recovery_target_time.

During recovery, WAL-E attempts to extract and restore all available WAL segments by default. If you want to restore a specific point in the time that you specify.

# restored at 16:38 on 06/03/2012
recovery_target_time = & # 39; 2012-03-06 16: 38: 00 & # 39;

I think the need should generate value every minute and insert into the table.

Insertion events found with CURRENT_TIMESTAMP

INSERT INTO events (ts, description) VALUES (CURRENT_TIMESTAMP, "full disk");

Found insert SELECT NOW ()

INTO INSERT indexing_table (created_at) SELECT NOW () FROM generate_series (1,100);

This is not an answer 🙁

recursion – System for solving loop differential equations with recursive variable

I've posted various questions on similar codes all year round, so if that sounds familiar, you may have seen another of my articles, but it's a problem unique that has not yet been laid. I'm posting it here. Basically, I use a loop, so solve a system of coupled differential equations, using these results to modify the value of a variable accordingly, and then solve the system again, this time with the new value of the variable that has been modified, and I wish to do this in small steps 200 times, then trace the output. Here is the code:

h2 = {{0, - (Ω / 2)}, {- (Ω / 2), δ0 + Δ}};

ρ2 = {{ρ11

ρdecay = {{1/2 * γ * ρ22

ρtderiv = -I * (h2.ρ2 - ρ2.h2) + ρdecay;

replace3 = {Δ -> -1 * 10 ^ 9, γ -> 1.6 * 10 ^ 9, Ω -> 1, m -> 10 ^ -25, -> 1 * 10 ^ -34, k -> ( Π) / (500 * 10 ^ -9), ν -> 10 ^ 3};

txvarray = Table[{0, 0, 0}, 200];

t0 = 0; ρ120 = 0; ρ210 = 0; ρ220 = 0; ρ110 = 1; δ0 = (2 π * 10 ^ 3) / (500 * 10 ^ -9);

Make[{}=Ρsol11ρsol12ρsol21ρsol22NDSolveValue[{Ρ11&#39;[{}=Ρsol11ρsol12ρsol21ρsol22NDSolveValue[{Ρ11'[{ρsol11ρsol12ρsol21ρsol22}=NDSolveValue[{ρ11'[{ρsol11ρsol12ρsol21ρsol22}=NDSolveValue[{ρ11'
At = 0.01;
t0 + = Δt;
fscatt = ℏ k ^ 2 γ Re[ρsol22[ρsol22[ρsol22[ρsol22[t0]]/ m /. replace3;
δ0 - = Δt fscatt;
txvarray[[i, 1]]= t0;
txvarray[[i, 2]]= fscatt;
txvarray[[i, 3]]= δ0;
ρ120 = ρsol12[t0];
ρ210 = ρsol21[t0];
ρ220 = ρsol22[t0];
ρ110 = ρsol11[t0], {i, 1, 200}]txabs = Table[{Txvarray[{Txvarray[{txvarray[{txvarray[[i, 1]], Abdos[txvarray[txvarray[txvarray[txvarray[[i, 3]]]}, {i, 1, 200}];

ListPlot[txabs, PlotStyle -> Green]

Note the δ0 on the front line, in h2. This is the variable that changes after each iteration (this happens in the line δ0 - = Δt fscatt;). The problem is that every time I try to run this code, it stays stuck and I have to leave the kernal. Any ideas why this is happening / how to fix it? Thank you!

linear algebra – How to represent the inverse loop in mathematics

I have a loop as follows:

as long as (n> 0)
{
p = p_this_minus_one * p_this;
p_minus_one = p;
not--;
}

Using the code mentioned above, I want to represent logic as follows:

P = (P_i-1 * P_i) * (P_i-2 * P_i-1) * (P_i-3 * P_i-2) …… up to (i-N)> 0

Can any one tell me how I can represent the formula described in math?
